Seems that BCM2835 does not support open-drain IO, but could it be possible to make sw emulation for it?

setup to opendrain

when output set to 1, configure as input and enable pullup (or allow pull-up configuration).
when output set to 0, configure as output and drive low.

Allow reading input state, when output set to 0, return 0, when set to 1 return true input value.
